Low Cement Castables
PRODUCTS
Lightweight Castable
Product Function
This product has the advantages of light volume, high compressive strength, acid and acid gas corrosion resistance. Heat insulation, heat preservation, low water absorption and other characteristics, simple construction, is the most ideal product for construction of alkali-resistant parts at high temperature. Good workability, strong adhesion, long initial setting time and construction operation time, rapid strength growth, strong impermeability, no need for acidification treatment, easy to ensure the compactness and fullness of masonry mortar joints, and can significantly improve the air tightness and integrity of the chimney lining wall and the corrosion resistance of the lining.
